Construction Site Water Quality Problems

Sediment runoff from construction sites can be significant and can impair streams, lakes, and rivers. This erosion is caused by stream bed scouring and habitat degradation, shoreline erosion, and stream bank widening, loss of fish population, and increased frequency of downstream flooding.

In addition, sediment often carries with it high loadings of metals, nutrients (such as phosphorus and nitrogen), and other pollutants which adversely affect the quality of downstream water bodies.
